Hence they are in fact demonstrably sharper.
What determines the amount of text that gets rendered on-screen is the software and how the software maps the logical screen size to the physical screen size. In other words, how the software uses the 480000 pixels available on both screens.
The software can choose to maintain the logical text size the same (using the same pixel count per character) and thus put up the exact same amount of text using slightly smaller characters or it can choose to maintain the physical text size which results in a larger pixel count per character and less text on the smaller screen. Either way the 5in screen will be sharper; through smaller pixels or more pixels per character.
All this assumes a competent renderer and a quality scalable font, of course.
With these Sony readers we can safely assume the same software so the software effects should be a wash and what remains is the physical differences of the screens themselves.
